Interest inventories are frequently validated against
group membership criteria. Two approaches are
considered, only one of which is commonly used.
The choice between the two approaches depends on
the application being validated. The first and most
common approach assumes that interest inventories
are to be used in predicting which occupation counselees
will enter or prefer. The second assumes that
interest inventories are to be used in suggesting occupations
for counselees to consider on the basis of
compatibility of interests. Validation of these two
uses of interest inventories requires different treatment
of criterion group base rates. As illustrated by
data drawn from a published study, the two approaches
to validation can produce substantial differences
in criterion group hit rates. Such differences
may be found in any study validating group
membership predictions if criterion group sizes vary
